JAMES WATERSTON. 



Thorax. Pronotum with a stout bristle above the spiracle, and a posterior row of 

 (S to 9 ; surface with moderately coarse reticulations and numerous (about IOC) 

 short bristles. Prostemite with coarse raised pattern. The mesonotum is similar 

 to that of S. glossinae, there being 60-70 short bristles on the mid lobe, 2 at the 

 post ero -lateral corners stronger, and over 12 on the side lobes ; the anterior bristle 

 hes well before one-half and the non-setigerous pustule is a little inwardly displaced. 

 The prepectus is coarsely reticulate ; the episternite lower down is extensively 

 rough, while the epimeron again is smoother. Keticulation of sternum most definite 

 posteriorly. Metanotum shining, not so roughened on notum and pleurae as in 

 glossinae. Propodeon entirely roughened (raised reticulate) ; the lateral keels- 

 posteriorly conveigent and the spiracle lying just inside the anterior angle. 





Fig. 8. Syntomosphyrum phaeosomay Wtrst., $ ; a, right wing ; h. radius ; 

 c, junction of marginal and submarginal. 



Wings (fig. 8) twice as long as broad ; length, 1 mm. ; breadth, 0*5 mm. ; 

 submarginal a little shorter than the marginal ; but roughly the proportions of 

 the veins are 4:4: 1. Submarginal with 3 bristles ; marginal fringe of 10 bristles ; 

 radius with 3 bristles. Hind wings, 0*9 mm. long, and four times as long as broad. 



Legs. The coxae, especially of the hind legs are coarsely raised reticulate above. 

 The first tibial comb consists of five spines and there are as many along the anterior 

 edge of the first fore tarsal joint. In the forelegs the proportions of the tarsal joints 

 are exactly as in glossinae, but the species differ in the posterior pairs.
